Checklist of Species

The following list of species does not claim to be definitive, but in the absence of full revision it gives some clue to the tortuous synonymies and the more important literature.

Phreatogammarus fragilis (Chilton), 1882. See below.

Phreatogammarus helmsii Chilton, 1918. See below.

Phreatogammarus propinquus Chilton, 1907. See below.

Ceradocus (Denticeradocus) chiltoni Sheard, 1939. Chilton, 1883, as Moera spinosa; 1916 as C. rubromaculatus. See also Pirlot, 1936 (fide Schellenberg, 1938). Two New Zealand species have been confused under C. rubromaculatus. The second is recorded from Australia by Chilton (1884) as Moera festiva and from New Zealand (1916) as Melita festiva. Stephensen, 1945, refers this to C. rubromaculatus Stimpson, but the figures given by Sheard, 1939, for the latter are at obvious variance with Chilton's given under Melita festiva in 1916. That there are two species is beyond question; what the generic and specific names of the second should be is still in some doubt.

Paracrangonyx compactus (Chilton), 1882. As Crangonyx compactus; also Chilton, 1894. Chilton, 1909a, as P. compactus.

Parapherusa crassipes (Haswell), 1880. Chilton, 1883, as Harmonia crassipes. Chilton, 1916a; Stephensen, 1949.

Melita gayi (Nicolet), 1849. Thomson, 1880, 1880a, as Melita tenuicornis; Chilton, 1909, as Melita inaequistylis; Schellenberg, 1931 and Stephensen, 1945, as M. gayi.
